STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
The following is a small section of RFC 1541 that governs lease expiration behavior:
4.4.4 Reacquisition and expiration ...
In both RENEWING and REBINDING state, if the client receives no
response to its DHCPREQUEST message, the client should wait one-half
the remaining time until the expiration of T1 (in RENEWING state) and
T2 (in REBINDING state) down to a minimum of 60 seconds, before
retransmitting the DHCPREQUEST message.
If the lease expires before the client receives a DHCPACK, the client
moves to INIT state, MUST immediately stop any other network
processing and requests network initialization parameters as if the
client were uninitialized. If the client then receives a DHCPACK
allocating that client its previous network address, the client SHOULD
continue network processing. If the client is given a new network
address, it MUST NOT continue using the previous network address and
SHOULD notify the local users of the problem.
